Nano-protection coating of the crystal

[Sojamannen]

Hello friends!

I am a new member of this forum, and I hope that I can contribute with interesting subjects!
I have also newly bought a Rolex Sea-Dweller Z-serial, my first Rolex! An amazing watch, totally uncompromised! It feels like if I have reached the end of searching “the watch” for a lifetime. This will be a "keeper" for life!

My profession is ILS (integrated logistic support) of optical and electrooptical devises for the Swedish Defence. We study a lot of different kinds of optical coating, even for after-market use.

One interesting area is the nano-technique-substances. There are quite lot of brands and products for nano-coating car windshields, glasses, motor cycle helmet visors, etc. The thing with nano- technique is that the rain and dirt repellent substance is split in to small particles in nano-size(0,000 000 001 mm). When you treat a glass surface, the small particles get almost inside the glass, creating a really hard bonding between the glass and the substance which can only be removed mechanically. The coated glass surface is now 1,5 to 2 times stronger then before against scratches, extreme flat and slippery, making it difficult for fingerprints, dirt and etc to stick. We are using this technique to protect the optics of binoculars, lenses, night vision devices, etc.

Has someone tried this coating method on a watch crystal? Wouldn’t be great if your Rolex crystal got 1,5 to 2 times stronger against scratches and easier to wipe off dirt from it?

What do you think? Any opinions?
